Parameters

selector The selector.

Return value

An enumerator over the available messages.

Remarks

The message is just being browsed, so it cannot be acknowledged. Because browsing messages allocates native resources, you
should call the Reset() method of the enumerator when you are done with it. If it is not called, the native resources are
not freed until this QAManagerBase object is freed.

Use QAManagerBase.GetMessage to receive messages so they can be acknowledged.
